This invention relates to dispensing receptacles and more particularly to an oil can used for applying lubricating oil to bearings, shafts and other moving parts of machmery. r

One object of the invention is to provide an oil can having a container or receptacle of relatively large capacity and improved means for dlscharging oil from the receptacle into a hearing or onto a shaft.

Another object of the invention is to so form the discharge means that when the oil can is in use quantities of oil may be withdrawn from the container by the discharge a paratus and ejected when the spout of the dischar e apparatus is by means of which it may be very easily held 90 and also to rovide improved actuatin means for the ischarge apparatus so locate that a trigger forming part of the same may be easily engaged with one finger of the hand a grasping the handle.

form the oil can that elements con ituting the same may be very easily taken apart when cleanin or repairs are necessary and then reassem led. I

The invention is illustrated in the accompanying drawing wherein Figure 1 is a longitudinal sectional view through the improved oil can,

Fig. 2 is a rear elevation thereof, Fig. 3 is a sectional view taken on the line 33 of Fig. 1, and Fig. 4 is a perspective view of a triggerengaging eye at the rear end of a piston r0 0 forming part of the ejecting apparatus.

The receptacle 1 of this improved oil can is preferably cylindrical n shape and at its forward end is provided with a head 2 perms. nently attached to walls of the rceeptacle. The rear end of the receptacle is closed by a removable head 3 consisting of a disk which applied to a bearing. Anot er object of the invention is to pro-* leakage at the vide the oil can with an improved handle Another object of the invention is to so,

.ing by the felt washer.

d Therefore, the rear or inner inwardly through the fits against the walls'where it is secured by a ring or collar 4 threaded upon the walls, as shown in Figure 1. A gasket 5 may be disposed between the head v3 and end ed es of the wallsin order to prevent danger of leakage. A filling opening 6 is formed in the walls and this opening is normall closed by a plug 7 havmg a vent 8 forme therein so that air may enter the receptacle as oil is discharged i p therefrom.

The barrel or cylinder 9 of the discharge apparatus extends longitudinally inthe receptacle with its rear end in threaded engagement with a cap 10 engaged through an open- .mg formed in the rear end 3 and gaskets 11 and 12 may be employed in order to revent rearend of this cylin er. neck ,13rextends forwardly from the front head 2 and through this neck is disposed a spent 14, the inner end of which is in threaded engagement with theforward end of the cylinder. It should be noted that the outer or forward e'ndportion 15 of the spout ie tapered and adjacentrits forward end carries a collar 16 against which is secured a washer '17 of felt or other suitable material so that when the tip of the spout is engaged in a bearing and oil forced through the spout into the bearing the oil will be confined in the bear- A valve seat 18 is provided at the forward end of the barrel for engagement by a valve ball 19 in the rear end portion of the spout and this valve ball is yieldably held in a closed position against its seat by a spring 20, the forward end of which bears against a pin 21 extending through the spout. end of the spout carries an outwardly opening check valve serving to permit oil to be freely discharged through the spout but preventm suction s out. mes the spout is in threaded en gement with the forward end of the cylin er,1t may be eas ly a detached therefrom when cleaning or repairs are necessary. A gland 22 engaged about the neck 13 serves to form a tight joint about the spout and prevent oil from leaking out of the receptacle.

Adjacent its forward end the cylinder or barrel 9 carries a tube 23 which extends downwardly in the receptacle and at its lower end carries a cap 24. This cap is threaded into place and is formed with a port 25 through which oil may pass from the receptacle into the tube. A screen 26 is applied to the cap in order to prevent sediment which may collect in the receptacle from entering the tube. Before the cap 24 is applied a yoke 27 is thrust into the tube to serve as an abutment for the upper end of a spring 28 by means of which a valve ball 29 is held in position to close the inner end of the port 25. Therefore, the tube will be provided with an inwardly or upwardly opening check valve serving to prevent oil from passing outward- 1y through the tube after being sucked into t e same.

When this oil can is in use, the oil is to be drawn through the tube 23 into the barrel or cylinder 9 and then forced outwardly past the check valve 19 and through the spout 14. In order to do so, there has been provlded a piston 30 similar in construction to the plston of a tire pump and having a piston stem or rod 31 which projects outwardly through and opening formed centrally in the cap 10. A handle 32 which resembles the rip of a piston is removably secured against t e head 3 by screws 33 passed throu h a flange 34 surrounding the shank 35 o the handle and this shank is hollowed to form a chamber 36 into which the outer end portion of the piston rod 31 extends. A trigger 37 which is pivotally mounted, as shown at 38, has its lower portion projecting outwardly through a slot 39 in the lower portion of the shank and the upper portion of the trigger is bent to form a hook 40 engaged through an eye 41 formed in a block or head 42 threaded into engagement with the rear end of the piston rod. It will be readily seen that when the handle is grasped in one hand and a finger engaged with the trigger the trigger may be moved to force the piston forwardly andcause oil to be forced past the check valve 19 and outwardly through the spout. When pressure upon the trigger is relieved, the spring 43 disposed about the piston rod between the cap 10 and a pin 44 passed through the piston rod moves the piston rearwardly. Th1s causes a suction to be created in the barrel and tube 23 and a fresh supply of oil will be sucked inwardly through the depending tube mto the barrel orcylinder. It will thus be seen that the oil can may be easily held by means of its handle and by actuating the trigger oil caused to be ejected through .the s out and as the piston moves rearwardl a resh supply of oil sucked into the barrel When repairs are necessary or it is desired to clean the oil can, the gland 22 is loosened after which the spout is unscrewed from the forward end of the barrel so that it may be drawn outwardly through the neck 13 and the ring 4 may then be unscrewed and the head 3 and barrel together with the tube 23 withdrawn as a unit from the receptacle. Necessary cleaning or repairs can then be performed and the oil can reassembled.
